.To all whom; it may concern.-

Be it known that LJEAN BAPrIsrE GUSTAVE ADOLIHE CANET G'DglIIGQQ a'citizen of the to ,theaccompanying drawings.--

This invention relates to firing mechanism forbreech-loading guns, andis more especially intended to be applied to quick-firing guns. It iswell known that such guns are commonly fired by striking a fulminatingor detonati'ng composition, it being usualto'act either directly orindirectly through a more or less rigid lanyard, which in practice isinconvenient. I

By my present invention I have overcome the objections which existagainst the firingdevices heretofore in use and I have provided 1 4mechanism whereby the firing hammer can be released with avery slighteifort on the partof the'guuner by means of a disengaging device whichis so constructed that all the parts thereof return automatically totheir original position after being released. In the accompanyingdrawings Wl1lCl1lllflS- tr'ate my invention, Figure'l is 'a longitudinalsection showing one form of my improved releasing apparatus. Fig. 2 is aplan of a pertionof said apparatus hereinafter described Figs. 3,4 and 5are transverse sections taken on the lines 3,3; 4:, 4; and 5,5'respectively of Fig. 1. Fig. 6 is a horizontal central section of thebreech end of a gun with the breechbloek in position, showing-thepercussive firing device constructed according. to a mod i-- fication ofmy invention. H

Like letters .deinOte corresponding throughout the drawings. Referringto Figs. 1 me, A cured toa non-recoilin g part of the gun mounting.

Bis the gun. t

O is a rod longitudinally niovable in beare parts .ings in the bracketA. -Thelrea r end-oflthe said rod 0 bears against the lever I) whichcontrols the trigger of the percussive firing mechanism.

E is a sleeve surroundingthe rod 0 and pro- I vided on its exteriorsurface with alongitudiis a bracket seaforesaid rib a. v

The forwardend of the rod 0 is enlarged ich for a pure to form a collaror head I) wh pose hereinafter described can engage with a spring hook Jfixed to the gun or to a part movable with the gun. The sleeve E isloose onthe rod'C and can turn thereon. It has formed at its forward endan eccentric collar 0' Figs. 2- and 3 the purpose of which is to pressback the spring J and disengage the sarn'o from thecollar b of the rod 0when the sleeveE is partially rotated as hereinafter described. Thenormal position of the one sided collar 0 is that shown in Fig. 3. Thesleeve E is supported at its forward end in a claw L which is secured inthe fixed bracket A, K is a pin fixed in the said claw L and whichpasses through a longitudinal slot' (1 rotation of the said rod when:the sleeve E is partially turned while allowing longitudinal movementofsaid rod. The said pin also at its rearend sufliciently wide to allow ofthe required-turning movementof the sleeve E and is of diminishing widthfrom its rear to its forward end at which extremity it is .onlylof thesame width as the pin K. One side of the said slot is made straight andparallel with the'axis of the sleeve, while the other side thereof asshown inFig. 2 is inclined as, and for a purpose, hereinafter described.

0 is'a ringsurrounding the rod (land inclosed in the sleeve E which ringis fixed by ,the pin K to the claw L. The said ringi constitntes anabutment for M which is inelosed in the sleeve E and the other end ofwhich presses against a collar N fixed on the rod 0. The said spring iscompressed when the rod (1 is pushed forward, and when released itserves to push the said rod back again. v

To place the device in a position ready 'for formed in the rod 0 therebypreventing the passesfhrough a longitudinal slote formed in the sleeveE. This latter slot however is one end of a spring use, the rod ispushed so far forward that the collar 2) engages with the hook J thesaid hook then retains the rod in this operative position wherein thelover D aforementioned bears against the rear extremity of the rod 0. Ifnow the releasing lever G is depressed, which it may be by a slightpressure of the finger, the short arm thereof operates the bar F andcauses the said bar which bears against the rib a of the sleeve E topartially rotate said sleeve whereupon the eccentrichead 0 of the saidsleeve acts on the spring- J and disengages the same from the collarb ofthe rod 0 as shown in Figs 2. The latter rod now being released isimmediately driven plained. Moreover during the recoil the hook J moveswith the gun and again becomes engaged with the collar 1) of the rod 0.The forward face of the said collar is inclined as shown in Figs. 1 and2 to permit the hook to slide past the collar during the recoil. iVhenthe gun runs out again the hook remains in engagement with the collar band thus'pulls the rod 0 and its sleeveE with it, and thereby compressesthe spring M readyfor the next firing. The firing-leverD is also by therunning out movement brought again in contact. or nearly so with the rodC. The parts are thus all restored to their initial position and areready to be operated again to fire the gun-by the pressing of the leverG in the manner above described.

In the firing mechanism at the side of the gun illustrated in Fi 6therod O is operated to effect the firing )y a spring M which iscompressed between a collar N fixed on the rod and the end of thebracket A. The said spring is inclosed in'a tubular part A fixed to thesaid bracket A.. Near its forward end the rod C is provided with a slot0 having oblique'ends C, C for a purpose hereinafter specified. Thespring hook J which isfixed to the gun or to apart that recoils with thegun is adapted to enter the said slot and-thus become engaged with therod O.- Whenso engaged with the rod the] curved face J of the hook bearsagainst the end of a pinGr which is adapted to slide axiallyin abearingin the bracket A, and the head of which serves as the pointofapplication ofa lever G8 which is pivoted at G to'the' bracket A. Thetail end of the lever G bears against and iscontrolled by the short armof the releasing lever G. The operation of this mechanism is as follows:that is to say, by pressing the releasing lever G, the pin G? is pushedinward *so' as to force the hook J out of the slot 0 and clear of therod 0 whereupon the spring M acts to drive the rodC backward and thusoperates the firing lever D to fire the gun. I In' the rearward movementof the rod C'the. oblique face 0 of the rod 0 is brought in contact withan inclined part G of the pin G and operates to press the said pinoutward again thereby replacing the levers G, G in their initialposition. By the recoil movement of the gun after firing, the springhook J moving with the gun is brought once more into a position whereinit can reenter the .slot C of the rod 0. Should the gun recoil beyondthis position the curved end of thehook will slide over the oblique face0 of the rod 0, returning over the said face when the gun again runs outso as to reenter the slot 0 and becomeengaged with" the rod 0. Thenthecontinued runningout with it and will compress the spring M, thusrestoring the parts to their initial position ready for the next firingoperation.

The remaining parts .illustrated in Fig. 6 areas follows: E is the gun;B is the breechblock'; B is the carrier bracket which is hinged to thegun on a pivot or hinge pin B in the usual manner.

ing pin, the point B" of which can project I P is a tube screwed.concentrically into the breech-block. Q, Q .are two rings or plugs thefirst named of ,movement of the gun .will carry the rod 0 beyondthe'face of the breech-screw; :Said

firingpin is controlled by a spring R which bearsagainst a collar 0"formed on the pin. Anotherv collar r formed on the pin forms a valvethe'seat of which is constituted by the ring Q. Said valve operatesto'prevent the access of powdergases to the breech-mechanism, in caseany'should escape past the rear end of the cartridge. Behind the pin Ris the firing hammer S-whieh is formed with whichis adapted to bescrewed'on the end of the tube P. There is. also "a bush 8- which abutsagainst the said nut and thereare also mounted on the hammer a. spiralspring S .and a sleeve S the latter'beingretained by a pin S passingthrough the hammerbut so constructed as to allow the sleeveSta. certainhammer with respect tothesleeveS. When these parts are in, place,thenut-S? isscrewed on the tube P and-the sleeve-Sibearsagainst,

T is a spring which is compressed between a shoulder formed on therod T and the bracket P, which spring operates to press the said rod inthe rearward direction. The inner spherical end D of the firing-leverDpreviously re-' ferred to engages with a second slot T formed in the rodT and operates to slide. the said rod to and fro when the said lever Dis oscillated about its pivot D The operation of this device-is asfollowsf, When the lever D is moved backward either by pulling-on alanyard fastened in the eye of the said lever or by the operation of thered C abovedescribed, the rod T is thereby moved forward and caused toturn the lever, o and through the detent S draw back the hammer S and Inthis movement, the cam portion of the lever 0 describes an 'arc of acircle while the detent S moves in a straight line, and consequently ata cer-' tain part of the movement the detent escapes from the cam 0' andreleases the hammer.

The latter thereupon is driven: forward by its spring until arrestedbythe sleeve S com ing in contact with the aforesaid internal shoulderof the tube P. Byreason however of the inertia acquired by the hammer,and the fact that it can move through the sleeve ,S for a'shortdistance, the hammer continues its forward movement'so far as tovstrikeand drive forward the firing pin and fire the gun. In so doing thehammer carries inward the bush 8 and operates to slightlyjcompress thespring S between thesaid bush and the sleeve St The hammer is thenbrought back to its initial position of rest by-its spring 3.

When the gun recoils, the lever'D is withdrawnffrom the red C and isthen free to re 4 turn to its initial position whichit does under thepressureof the'spring'T and atthe same time turns back-the lever oandoaus'es the cam part 0 of saidgle'v'er to force back and then tore-engagewith the spftihg detent S. -Allthe parts of thefiring-mechanism-are thus returned to theirinitial'position, ,To preventfi ting before the breech-screw is properly screwed home, I so arrangethat, the forward end;ofthe r'od'T shall be in close proximity to therear end of the breech-screw and I provide a recess 8' in thebreech-screw in such position that said recess is in line with the, rodT when and my when the The rod T can bev moved forward to fire the gun;

breech-screw isproperly screwed home.

when but not until the recess 'is'oppos'ite' the end'of the rod, thatisto say, when-the breech is properly closed.
